Two Southie brothers were held without bail after they were arraigned for urinating on and stomping a sleeping Hispanic homeless man, an attack police say was semi-inspired by the firey words of Republican presidential candidate Donald Trump.

As the paramedics took him to Boston Medical Center, a homeless man told investigators that when he woke up, two men were urinating on him. They then ransacked his belongings and beat him with their fist and a metal pole.

Scott and Steve Leader pleaded not guilty to several counts of assault and battery with a dangerous weapon, indecent exposure and making threats in Dorchester District Court on Wednesday.

Assistant District Attorney Andrew Kettlewell recommended they be held without bail, saying that there was “clear and convincing evidence that no conditions of release will reasonably assure the safety of any other person or the community.”

State Police troopers assigned to the South Boston barracks were on patrol at about 12:30 a.m. Wednesday when they responded to a report of two men beating another with a metal pole at the JFK/UMass T station. Witnesses told authorities that two men beat a sleeping 58-year-old homeless man, and walked away laughing. The man was treated for a broken nose, serious bruising to the torso and other injuries.

“These allegations are sickening,” Suffolk County District Attorney Dan Conley said. “Withholding bail was absolutely appropriate given the facts as we understand them. Just as important, however, is that several witnesses stepped up, contacted police and gave full statements when they witnessed a vicious, unprovoked crime. They did the right thing here, and we’re grateful to them for recognizing the urgency of the situation.”

According to the DA, both brothers were well known to the police.

Scott Leader allegedly made a series of incriminating statements, including that he and his brother “tuned up” an “illegal immigrant,” and that their actions were acceptable because the victim was homeless and Hispanic.

Police say he told them, “Donald Trump was right. All of these illegals need to be deported.”

When told of the assault, Trump told the Boston Globe: “It would be a shame . . . I will say that people who are following me are very passionate. They love this country and they want this country to be great again. They are passionate," the Globe reported.

The Boston Globe reported that Scott Leader spent a year locked up for a hate crime after he attacked a Moroccan man in Boston a few days after Sept. 11 in reaction to the terrorist attacks.

Steve Leader allegedly exposed his genitals to the troopers several times and urinated on the door and floor of the cell block. He allegedly stated that he would “kick the [expletive]” out of the troopers if he weren’t in the cell.

This attack came on the same day as an immigrants rights rally at the State House, where activists called on Gov. Charlie Baker to change his stance on laws designed to help undocumented immigrants. They also used the rally as a chance to call out the dangerous xenophobic language Trump has used in discussing immigration, which has helped him soar in voter polls.
